"Alexa," as Amazon calls the digital assistant inside the Echo, is like her personal butler.

But it's sometimes too helpful, Schiller says. She discovered the device can order things from Amazon with almost no effort, sometimes things you don't want.

It happened last week. She was watching the news, which ran a story about one family's Echo ordering an expensive dollhouse when a young child asked Alexa for one.

The family, it turns out, had not set any safeguards on the unit, so the sale went through as if they had made a "one click" Amazon Prime purchase. The dollhouse showed up on their doorstep a few days later.

But Schiller can't believe what happened next: After hearing the report on the TV, her Alexa started ordering a dollhouse too.

"The TV was loud enough to where my Echo picked it up and was ready to order a dollhouse," she said.

"They actually went through the exact words the little girl said," Schiller said. "And when that happened, the TV was loud enough my Echo picked it up and the TV was ready to order a dollhouse!"

Luckily she yelled out "Cancel," to stop the order.

And she says it is a good thing she didn't have any kids at home at the time.

"All they probably had to say was 'yes,' and it would be in the mail." Schiller said.

Turns out there is a simple solution to your Echo device ordering something when someone says "Alexa I'd like something."

She discovered all you have to do is add an ordering password, to prevent a pricey item from showing up on your doorstep.

With a password, you have to confirm each order before it goes through. There's no chance of a 3-year-old ordering a $150 dollhouse, or anything else, so you don't waste your money.
